Costs of Early Childhood Home Visiting: An Analysis of Programs Implemented in the Supporting Evidence-Based Home Visiting to Prevent Child Maltreatment Initiative

The Cost Study of Evidence-Based Home Visiting Programs applied a uniform approach and common time frame to analyze costs among agencies implementing five different home visiting program models. The study assessed (1) the total cost of providing home visiting programs during a year of steady-state operation, (2) the allocation of annual costs among cost categories and program activities or components, (3) the cost to serve a participating family, and (4) variation in average costs across program models and other agency characteristics.Mathematica Policy Research and Chapin Hall at the University of Chicago conducted the study with support from the Doris Duke Charitable Foundation and in collaboration with Casey Family Programs. It included agencies that participated in the Supporting Evidence-Based Home Visiting to Prevent Child Maltreatment (EBHV) initiative, a five-year grant program launched in 2008 by the Children's Bureau of the Administration for Children and Families at HHS. In 2011, the EBHV grant program was formally incorporated into the Maternal, Infant and Early Childhood Home Visiting Program (MIECHV) State Formula Grant Program administered by the Health Resources and Services Administration of HHS

Social Perspective Taking

The current mindset of the Army is that it must be able to win our Nation’s wars while at the same time ready to assist in stability operations (U.S. Department of the Army, 2008). A challenge is that Soldiers often have to bridge large cultural gaps and may lack the language skills to effectively engage with the host of individuals now present in these operations including the local populace, host nation security forces, coalition partners and other foreign governmental and nongovernmental agencies. Perspective taking – described more formally as “Social Perspective Taking” (SPT) – is an interpersonal technique which may address these challenges. SPT is a skill often learned throughout life but may be very difficult in cross-cultural interactions. This report describes the results of a literature review and SME and Soldier interviews regarding the knowledge, skills, and abilities (KSAs) needed to develop SPT and the methods used to train SPT. Based on this information a four module curriculum is proposed which utilizes a four-step method for the development of SPT. The curriculum trains Soldiers how to accurately consider the host-national’s perspective without cultural bias and erroneous assumptions and allows Soldiers to meet host-national goals while accomplishing U.S. missions and objectives

Weaving Together Indigenous and Western Knowledge in Science Education: Reflections and Recommendations

The Culturally Responsive Indigenous Science (CRIS) project was a collaborative effort between three Tribal communities in the Pacific Northwest and faculty and students from Washington State University, many of who are Tribal citizens. The project was designed to integrate Indigenous Traditional Ecological Knowledge (ITEK) and Western Knowledge into science curricula and professional learning opportunities. At the end of the 5-year grant project, members of the CRIS team (including Tribal and university partners) gathered to reflect on the work accomplished and the lessons learned about the process of integrating ITEK within science education. In this conceptual paper, the authors discuss four key takeaways from their reflections: 1) Creating relational space for cultural values and practices, 2) Indigenous science education requires many educators with diverse expertise, 3) Respecting Tribal and individual autonomy and timelines, and 4) Remembering who the work is meant to serve. In summary, the authors highlighted important recommendations to be considered when weaving together ITEK and Western science to better serve and engage Native American youth

Community Engagement, Trust, and Genetic Testing for Inherited Diseases Among Adopted Persons

We identify concerns pertinent to establishing trust necessary to support adoptees’ confidence in and uptake of genetic testing that might allow them to benefit from early screening and medical intervention. Using principles of community-based participatory research, our study sought to build a foundation of trust to document such perspectives. Three focus groups were held with 12 adult adoptees. Transcripts were analyzed using thematic content analysis. Comments highlighted aspects related to genomics and health history in the context of adoption, specifically: (1) trust in the intention of the research study; (2) trust that the adoption community will benefit from the results of research; and (3) trust in the protection from misuse and abuse of genomic data. Results reinforce the call for proper security of data and oversight of the ways it is used and point to the value of including researchers who are a part of the community under study

Improving atmospheric CO\u3csub\u3e2\u3c/sub\u3e retrievals using line mixing and speed-dependence when fitting high-resolution ground-based solar spectra

A quadratic speed-dependent Voigt spectral line shape with line mixing (qSDV + LM) has been included in atmospheric trace-gas retrievals to improve the accuracy of the calculated CO2 absorption coefficients. CO2 laboratory spectra were used to validate absorption coefficient calculations for three bands: the strong 20013 ← 00001 band centered at 4850 cm−1, and the weak 30013 ← 00001 and 30012 ← 00001 bands centered at 6220 cm−1 and 6340 cm−1 respectively, and referred to below as bands 1 and 2. Several different line lists were tested. Laboratory spectra were best reproduced for the strong CO2 band when using HITRAN 2008 spectroscopic data with air-broadened widths divided by 0.985, self-broadened widths divided by 0.978, line mixing coefficients calculated using the exponential power gap (EPG) law, and a speed-dependent parameter of 0.11 used for all lines. For the weak CO2 bands, laboratory spectra were best reproduced using spectroscopic parameters from the studies by Devi et al. in 2007 coupled with line mixing coefficients calculated using the EPG law. A total of 132,598 high-resolution ground-based solar absorption spectra were fitted using qSDV + LM to calculate CO2 absorption coefficients and compared to fits that used the Voigt line shape. For the strong CO2 band, the average root mean square (RMS) residual is 0.49 ± 0.22% when using qSDV + LM to calculate the absorption coefficients. This is an improvement over the results with the Voigt line shape, which had an average RMS residual of 0.60 ± 0.21%. When using the qSDV + LM to fit the two weak CO2 bands, the average RMS residual is 0.47 ± 0.19% and 0.51 ± 0.20% for bands 1 and 2, respectively. These values are identical to those obtained with the Voigt line shape. Finally, we find that using the qSDV + LM decreases the airmass dependence of the column averaged dry air mole fraction of CO2 retrieved from the strong and both weak CO2 bands when compared to the retrievals obtained using the Voigt line shape

NH3 spatiotemporal variability over Paris, Mexico City, and Toronto, and its link to PM2.5 during pollution events

Megacities can experience high levels of fine particulate matter (PM2.5) pollution linked to ammonia (NH3) mainly emitted from agricultural activities. Here, we investigate such pollution in the cities of Paris, Mexico, and Toronto, each of which have distinct emission sources, agricultural regulations, and topography. Ten years of measurements from the infrared atmospheric sounding interferometer (IASI) are used to assess the spatiotemporal NH3 variability over and around the three cities. In Europe and North America, we determine that temperature is associated with the increase in NH3 atmospheric concentrations with a coefficient of determination (r2) of 0.8 over agricultural areas. The variety of the NH3 sources (industry and agricultural) and the weaker temperature seasonal cycle in southern North America induce a lower correlation factor (r2=0.5). The three regions are subject to long-range transport of NH3, as shown using HYSPLIT cluster back trajectories. The highest NH3 concentrations measured at the city scale are associated with air masses coming from the surrounding and north/northeast regions of Paris, the south/southwest areas of Toronto, and the southeast/southwest zones of Mexico City. Using NH3 and PM2.5 measurements derived from IASI and surface observations from 2008 to 2017, annually frequent pollution events are identified in the three cities. Wind roses reveal statistical patterns during these pollution events with dominant northeast/southwest directions in Paris and Mexico City, and the transboundary transport of pollutants from the United States in Toronto. To check how well chemistry transport models perform during pollution events, we evaluate simulations made using the GEOS-Chem model for March 2011. In these simulations we find that NH3 concentrations are underestimated overall, though day-to-day variability is well represented. PM2.5 is generally underestimated over Paris and Mexico City, but overestimated over Toronto.</p

Measurement report: Evolution and distribution of NH3_3 over Mexico City from ground-based and satellite infrared spectroscopic measurements

Ammonia (NH$_3$) is the most abundant alkaline compound in the atmosphere, with consequences for the environment, human health, and radiative forcing. In urban environments, it is known to play a key role in the formation of secondary aerosols through its reactions with nitric and sulfuric acids. However, there are only a few studies about NH$_3$ in Mexico City. In this work, atmospheric NH$_3$ was measured over Mexico City between 2012 and 2020 by means of ground based solar absorption spectroscopy using Fourier transform infrared (FTIR) spectrometers at two sites (urban and remote). Total columns of NH$_3$ were retrieved from the FTIR spectra and compared with data obtained from the Infrared Atmospheric Sounding Interferometer (IASI) satellite instrument. The diurnal variability of NH$_3$ differs between the two FTIR stations and is strongly influenced by the urban sources. Most of the NH$_3$ measured at the urban station is from local sources, while the NH$_3$ observed at the remote site is most likely transported from the city and surrounding areas. The evolution of the boundary layer and the temperature play a significant role in the recorded seasonal and diurnal patterns of NH$_3$. Although the vertical columns of NH$_3$ are much larger at the urban station, the observed annual cycles are similar for both stations, with the largest values in the warm months, such as April and May. The IASI measurements underestimate the FTIR NH$_3$ total columns by an average of 32.2 ± 27.5 % but exhibit similar temporal variability. The NH$_3$ spatial distribution from IASI shows the largest columns in the northeast part of the city. In general, NH$_3$ total columns over Mexico City measured at the FTIR stations exhibited an average annual increase of 92 ± 3.9 × 10$^{13}$ molecules cm$^{−2}$ yr$^{−1}$ (urban, from 2012 to 2019) and 8.4 ± 1.4 × 10$^{13}$ molecules cm$^{−2}$ yr$^{−1}$ (re- mote, from 2012 to 2020), while IASI data within 20 km of the urban station exhibited an average annual increase of 38 ± 7.6 × 10$^{13}$ molecules cm$^{−2}$ yr$^{−1}$ from 2008 to 2018

Observations of Extreme Wildfire Enhancements of CH3OH, HCOOH, and PAN over the Canadian High Arctic

Wildfires are a common occurrence in many parts of the globe and can emit significant quantities of trace gases and particulate matter, negatively impacting air quality on large spatial scales. Among the various trace gases emitted by wildfires are volatile organic compounds (VOCs). Three VOCs that are of particular importance are methanol (CH3OH), formic acid (HCOOH), and peroxyacetyl nitrate (PAN). CH3OH is the one of the most abundant VOCs in the atmosphere, and it influences the budgets of many tropospheric species including the hydroxyl radical, carbon monoxide, formaldehyde, and ozone. HCOOH is the most abundant tropospheric carboxylic acid, and thus can have significant impacts on atmospheric acidity, particularly in remote regions such as the Arctic. Lastly, PAN is a key, thermally unstable reservoir species of tropospheric nitrogen radicals (NOx = NO + NO2), controlling the production of tropospheric ozone, and contributing to the ‘Arctic haze’ pollution phenomenon at high latitudes.During August 2017, two independent large-scale wildfires in British Columbia and the Northwest Territories of Canada generated vast smoke plumes that merged and were subsequently transported to the high Arctic. Simultaneous observations by a high-resolution ground-based Fourier transform infrared (FTIR) spectrometer at the Polar Environment Research Laboratory (PEARL) in Eureka, Nunavut (80.05°N, 86.42°W), and the Infrared Atmospheric Sounding Interferometer (IASI) satellite instruments display extreme enhancements in these three species relative to background concentrations during the fire-affected period in late August 2017, demonstrating the long-range transport and secondary formation of these typically short-lived species. Initial results of the analysis of this unique biomass burning event will be presented, including comparisons of observations with the GEOS-Chem global chemical transport model.info:eu-repo/semantics/nonPublishe
